It is very near to green line BTS station; definitely ideal if you are planning to use the train throughout your visit.
Generally clean; there's nothing much to complain. Rooms were clean, no odour/smell, not too dusty, trash bins were emptied, and etc. Toilet bowls were squeaky clean (not yucky or yellowish), toilet floors were always dry, not moldy, nor have odour.
Friendly and helpful hosts.
